The olfactory epithelium is a specialized epithelial tissue inside the nasal cavity that is involved in smell. In humans, it measures about 9 cm 2 (3 centimeters by 3 centimeters) and lies on the roof of the nasal cavity about 7 cm above and behind the nostrils.
1 The olfactory segment is lined with a specialized type of pseudostratified columnar epithelium, known as olfactory epithelium, which contains receptors for the sense of the smell. 2  This segment is located in and beneath the mucosa of the roof of each nasal cavity and the medial side of each middle turbinate.nnervation of the nasal cavity responsible for the sense of smell is via the olfactory nerve, which sends microscopic fibers from the olfactory bulb through the cribriform plate to reach the top of the nasal cavity.
